[1] Non-vested restricted stock units at each period included shares to certain non-employee directors in which vesting will occur immediately if the relationship between the Company and the non-employee director ceases for any reason, subject in the case of voluntary resignation to the consent of the Compensation Committee to the immediate vesting. These non-vested shares were recognized and fully expensed as stock-based compensation in the Condensed Statements of Income at the date of grant or the date of modification.
